6.5.7 System Integration
A variety of standard system functions are integrated into the device, including:
- Direct memory access (DMA) controller (see Section 6.5.7.1)
- System control and clocks including on-chip precision 16-MHz oscillator (see Section 6.5.7.2)
- Eight 32-bit timers (each timer can be configured as two 16-bit timers) (see Section 6.5.7.3)
- Lower-power battery-backed Hibernation module (see Section 6.5.7.5)
- RTC in Hibernation module
- Two watchdog timers (see Section 6.5.7.6)
- One timer runs off the main oscillator.
- One timer runs off the precision internal oscillator.
- 90 GPIOs, depending on configuration (see Section 6.5.7.7)
- Highly flexible pin multiplexing allows use as GPIO or one of several peripheral functions.
- GPIOs are independently configurable to 2-, 4-, 8-, 10-, or 12-mA drive capability.
- Up to 4 GPIOs can have 18-mA drive capability.
